How can I Move data from one column to another in my access table?

Question

I have two columns, one that stores current month’s data and one that stores last month’s data. Every month data from column 2 (this month’s data) needs to be moved to column 1 that holds last month’s data. I then null out column 2 so I can accumulates this month’s data.
I understand how to drop a column or add a column, how do I transfer data from one column to another.
Here is my trial code:
<cfquery name="qQueryChangeColumnName" datasource="#dsn#">
  ALTER TABLE leaderboard
  UPDATE leaderboard SET  points2 = points3
</cfquery>
Unfortunately, I get the following error:
Error Executing Database Query.
[Macromedia][SequeLink JDBC Driver][ODBC Socket][Microsoft][ODBC Microsoft Access Driver] Syntax error in ALTER TABLE statement.
How can I transfer my data with the alter table method?

Answer 1

I looked up the Access SQL reference (which is probably a
good place to start when having issues with Access SQL), and
it suggests you probably need a WHERE clause in there.
I agree the documentation is a good place to start. But you should not need a WHERE clause here.
Too few parameters. Expected 1.
If you run the SQL directly in Access, what are the results? At the very least, it should provide a more informative error message..
